To all whom it may concern:

Be it known that I, VVILLIAM GUTEN- KUNST, a citizenof the United States, residing at the city of Milwaukee, county of Milwaukee, and State of i/Visconsin, have invented new and useful Improvements in Portable Milk-Stools, of which the following is a specification.

My invention relates to improvements in that class of milk stools which are adapted to be temporarily clamped to a vertical standard in a stable, and it pertains more especially, among other things, to the spring actuated mechanism by which the stool is prevented from becoming'accidentally disengaged from its supporting standard.

My invention is explained by reference to the accompanying drawings, in which- Figure 1 is a side view. Fig. 2 is a plan view drawn on line 00, w of Fig. 1, looking downward. Fig. 3 is a horizontal section drawn on line y, y of said Fig. 1. Figs. 4, 5 and 6 are modified forms of the'device shown in Figs. 1, 2 and 8.

Like parts are identified by the same reference numerals throughout the several views.

1 represents the seat of the stool, which is preferably revolubly supported from the bracket 2 on a revoluble trunnion 3, and said trunnion 3 is retained in. a suitable aperture provided therefor in said bracket and prevented from being withdrawn therefrom by the pin 4.

5 represents a standard to which the stool is temporarily attached. The standard 5 may, of course, be located either in a stable or elsewhere as circumstances may require. The bracket 2 is provided with two clamping members 8 which are adapted to partially surround the standard 5. The clamping members 8 are adapted to extend partially around and bear against two opposing sides of said standard 5, and are retained in place by the pivotal bolts 9, 9. Each of the clamping members8 is provided with a hand actuated lever 10 by which the opposite end is thrown out of contact with said standard when desired to move the stool therefrom.

11 is a spiral spring which is interposed between the levers 10, and said spring is adapted by its recoil to force the free ends of said levers 1O outward and away from the bracket while the clamping members 8 are caused to impinge against the sides of said standard.

recoil of said spring 11, whereby the stoolwill be retained at any desired elevation.

In the modified form shown in Figs. 4, 5 and 6 the seat 1, bracket 2, trunnion 3, pin 4, standard 5, and member 6 are all substantially like those shown in Figs. 1 and 2. In the modified form, however, a single movable clamping arm 8 is used instead of two movable clamping members 8, shown in Fig. 2, and the spring 11 is adapted to bear at one end against the bracket 2 and at its opposite end against the lever 10' instead of against two levers 10, as shown in Fig. 3.

Attention is called to the fact that by both constructions when the standard 5 is brought in place between the clamping members 8 or between the clamping member 8 and the stationary arm 7 such standard 5 is adapted to bear against the short arms 13, 18, shown in Figs. 2 and 3, or against the short arm 13, shown in Figs. 5 and 6, whereby the clamping members 8 or 8 are forced into rigid contact with said vertical member '5, whereby the stool is prevented from slipping down on said vertical member and is rigidly retained at any desired point of adjustment. Attention is also called to the fact that in both the preferred and modified forms shown the bracket 2 is provided with a lateral projecting lug 14, which as the seat 1 is raised in the act of removing the stool from the standard 5 is adapted to contact with said standard 5 and limit the upward movement of said seat as the clamping members 8 or 8 are being withdrawn from said standard 5. By the device shown in Figs. 1, 2 and 3 the clamping members 8 are pivotally supported from the lugs 15, 15 by the bolt 9, while the clamping member 8 is pivotally supported from the lugs 17 by the bolts 9.

Having thus described my invention, what I claim as new and desire to secure by Letters Patents, is

1. In a device of the described class, the combination of a seat supporting bracket, a circular member connected with the upper side of said bracket, a pair of movable clamping arms pivotally connected with the.

lower side or" said bracket, said arms being adapted to impinge against two opposing sides of said vertical standard, and to be prevented'by their frictional contact with said standard from moving downward thereon.

2. In a device of the described class, the

combination of a seat supporting bracket, a

circular member connected with the upper side of said bracket, two clamping arms pivotally connected with the lower side of said bracket, and adapted to impinge against two lopposing sides of a vertical standard, and a spring adapted to temporarily retain said clamping arms in contact with said supporting standard. .3, The combination of a seat supporting bracket, a circular member connected with the upper sideof said bracket, a pair of clamping arms pivotally connected with the lower side of said bracket, and adapted to engage two opposing sides of a vertical standard, a lug formed integral with each of said clamping arms adapted to contact said bracket, and adapted to engage two opposing sides of a vertical standard, anda spring adapted to temporarily retain said pair of arms in contact with said vertical standard.

In testimony whereof I affix my signature in the presence of two Witnesses.
